J. K. Rowling

We did it, we bashed them, wee Potter's the one,
And Voldy's gone moldy, so now let's have fun!

“Who wrote this? Ah… of course… Rita Skeeter.”
“That woman’s got it in for the Ministry of Magic!” said Percy furiously. “Last week she was saying we’re wasting our time quibbling about cauldron thickness, when we should be stamping out vampires! As if it wasn’t specifically stated in paragraph twelve of the Guidelines for the Treatment of Non-Wizard Part Humans—”
“Do us a favor, Perce,” said Bill, yawning, “and shut up.”

“Hello,” said a vague and dreamy voice from behind them. Harry looked up: Luna Lovegood had drifted over from the Ravenclaw table. Many people were staring at her and a few were openly laughing and pointing; she had managed to procure a hat shaped like a life-size lion’s head, which was perched precariously on her head.
“I’m supporting Gryffindor,” said Luna, pointing unnecessarily at her hat. “Look what it does…”
She reached up and tapped the hat with her wand. It opened its mouth wide and gave an extremely realistic roar that made everyone in the vicinity jump.
“It’s good, isn’t it?” said Luna happily. “I wanted to have it chewing up a serpent to represent Slytherin, you know, but there wasn’t time. Anyway… good luck, Ronald!”

...nice Bludger from Fred Weasley, I mean, George Weasley, oh who cares!

The warm glow that had flared inside him at the sight of his two best friends was extinguished as something icy flooded the pit of his stomach. All of a sudden — after yearning to see them for a solid month — he felt he would rather Ron and Hermione left him alone.
